DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The present invention will be clearer from the following description when viewed together with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment in accordance with the present invention.

Referring to FIGS. 2-6, an adjustable exercising tubing comprises two grip members 1 and three resilient straps 2, wherein each of the grip members 1 includes a body 11, an engaging member 12, an elastic element 13, and a positioning cover 14. The body 11 includes a lateral coupling seat 111 having three inserting holes 112 disposed on a front end thereof and a handle 113 extending from a rear end thereof to connect with a hanging rope 114, the handle 113 is filled with foam material, and the coupling seat 111 further having a sliding groove 115 fixed on a side thereof, communicating with the inserting holes 112 and being in response to a cross section of the engaging member 12 to be formed in a projection shape, and having a retaining recess 116 secured on an opening end of the sliding groove 115. The engaging member 12 includes a pushing portion 121 fixed on a top surface thereof and a notch 122 arranged on an inner wall thereof and three locking projections 123 disposed on a bottom thereof, each locking projection 123 having a beveled surface 1231 mounted on a front end of one side thereof. The elastic element 13 is formed in a lamination shape, such as a spring, and the resilient strap 2 has a proper elasticity and a connector 21 fixed on each of two ends thereof, the connector 21 includes an engagement slot 211 or engagement bore arranged on one side thereof.

In assembly, one end of the elastic element 13 is fitted into the notch 122 of the engaging member 12, and then the elastic element 13 and the engaging member 12 are fitted to the sliding groove 115 of the body 11. The positioning cover 14 is covered to the retaining recess 116 of the body 11 to limit the engaging member 12 not disengage from the sliding groove 115 of the body 11 so that the elastic element 13 is pressed to abut against an inner side of the notch 122 of the engaging member 12 by using its one end, and another end of the elastic element 13 is biased against an inner side of the sliding groove 115, and then the connectors 21 of the two ends of the resilient strap 2 are inserted to the inserting holes 112 to push against the beveled surface 1231 of the locking projection 123 of the engaging member 12, the elastic element 13 is compressed to drive the engaging member 12 to slide horizontally, and as the connectors 21 are inserted to predetermined positions, the engaging member 12 is pushed by the elastic element 13 to move back to it original position, and the locking projection 123 is retained in the engagement slot 211 of the connector 21, finishing assembly.

In operation, the two grip members 1 are held by user to be pressed inward to twist the resilient straps 2, and then after the user releases the resilient straps 2, the resilient straps 2 recovers its resilience to exercise arms and chest.

As shown in FIG. 7, as desiring to remove the resilient straps 2, the engaging member 12 is pushed away from the sliding groove 15 by pushing the pushing portion 121 so that the elastic element 13 compresses the locking projections 123 of the engaging member 12 to disengage from the engagement slots 211 of the connectors 21 of the resilient straps 2, and then the connectors 21 of the resilient straps 2 are pulled away from the inserting holes 112 of the body 11.

Referring to FIGS. 8 and 9, one or two resilient straps 2 are selected to be inserted to the inserting holes 112 located on two outer sides of the coupling seats 111 or the inserting holes 112 located on a middle portion thereof.

It is apparent form the above description that the adjustable exercising tubing of the present invention has the following advantages:

1. The number of the resilient straps 2 is selective based on requirement to assemble to and disassemble from the predetermined inserting holes 112 easily, adjusting desired resiliently twisted resistance.

2. In assembly, the resilient straps 2 are inserted to the inserting holes 112 directly. Also, by pushing the engaging member 12 outward, the resilient straps 2 are disassembled quickly.

3. The resilient straps 2 are located between the handles 1, preventing the resilient straps 2 from injuring user.

4. The resilient straps 2 and the grip members 1 allow to be assembled and disassembled according to required number to decrease storage size.
